A flash flood tore through a remote mountain village in northern Vietnam early Friday, killing at least four people, leaving four others missing and injuring seven, as days of relentless rain overwhelmed the country’s mountainous north and triggered a cascade of landslides across the region.
The flood struck Muong Than village in Lai Chau province, according to the Vietnam News Agency, sweeping away homes and roads in a commune already battered by a week of torrential downpours. The hardest hit regions include Muong Than and Than Uyen communes in Lai Chau, alongside Ngoc Chien commune in Son La. Heavy rainfall triggered the torrents of floodwater to flow from mountains more than 1,000 m high down to the plains.
According to the National Centre for Hydro-Meteorological Forecasting, the Phuc Than observation station recorded 206 millimetres of rainfall in the 24 hours to 9 a.m. Friday. Most of that rain fell overnight and into the early morning hours, causing the flood risk to escalate rapidly and leaving many residents with little warning before the water hit.
The deluge also inflicted serious damage on National Highway 32, a key route connecting Hanoi with Phu Tho, Lao Cai and Lai Chau provinces. In Hamlet 11 of Muong Than Commune, the force of the floodwater brought down several two-storey houses standing along the highway, while long stretches of the road itself were torn apart, severing a vital transit link for the region.
A Village Buried in Mud
Images released by the Vietnam News Agency showed the aftermath in stark detail, with red mud and floodwater blanketing the village and rocks and splintered wood logs piled against a damaged road, evidence of the sheer force with which the water tore through the area. Local reports said the disaster destroyed 13 houses outright, while state media said the search for survivors was ongoing even as one body had already been recovered.
One of the dead, a man in his forties, was found in the Muong Mit hydroelectric reservoir, according to communal police cited by Vietnam News. Search teams were continuing to look for four people still unaccounted for: 31-year-old Lo Van Chuong, a resident of Chit village; 22-year-old Pham Thi Lien, from Than Uyen commune; and two children, 11-year-old Pham Bao Cham and eight-year-old Pham Xuan Truong.
Days of Heavy Rain Set the Stage for Disaster
The flood was the culmination of days of extreme weather across northern Vietnam. Since Wednesday, landslides and flash floods triggered by heavy rain have damaged roads, power grids and hundreds of houses, according to state media, while also inundating 238 hectares of agricultural land. Vietnamese authorities warned the danger was far from over, forecasting that several parts of the region could see up to 250 millimetres of additional rainfall on Saturday, a level of precipitation officials said raises the risk of further flash floods and landslides in the days ahead.
A Recurring Toll in Vietnam’s Rainy Season
The disaster is the latest reminder of Vietnam’s chronic vulnerability to extreme weather during its rainy season, which typically peaks between July and September. Natural disasters, most of them floods, killed 489 people across the country last year, according to government data, and mountainous provinces such as Lai Chau are especially exposed because of steep terrain that channels heavy rainfall into sudden, violent surges. Scientists have linked the growing intensity of such storms to human-driven climate change, which is producing heavier and more erratic rainfall patterns across South East Asia.
Friday’s flood echoes previous disasters that have struck Vietnam’s north in recent summers, including a flash flood in Son La province last July that killed five people and destroyed 22 homes, and Typhoon Yagi in 2024, which left 345 people dead and caused an estimated $3.3 billion in economic damage. With rescue operations for the four missing residents still underway and more heavy rain forecast through the weekend, officials in Lai Chau face a race against time even as the broader region braces for the possibility of further flooding.
